Add ENV_STAGE_SUPPORTS_SMP to clean up spinlock stubs
CONFIG(SMP) was an invalid condition to use in cases where one stage requires spinlocks and another one does not. The stage not requiring spinlock still required <smp/spinlock.h> to be implemented with no-op stubs. This reverts commit 037ee4b556 soc/amd/picasso: Add dummy spinlock for psp_verstage Change-Id: Iba52febdeee78294f916775ee9ce8a82d6203570 Signed-off-by: Kyösti Mälkki <kyosti.malkki@gmail.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/59094 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Raul Rangel <rrangel@chromium.org> Reviewed-by: Julius Werner <jwerner@chromium.org>
